The Prostate gland
The prostate is a walnut-sized organ that surrounds the
first part of the urethra. It is located between the bladder and the penis. Semen
is formed by the prostate by combining a thick white fluid it initially produced
with the sperm from the testicles. It also produces an antibiotic protein known
as prostate-specific antigen (PSA) that changes the semen into liquid.
The muscle elevates and/or adducts a region.
When the structure and function of an organism adjusts to its environment it is adapting.
Rainforest plants have evolved waxy coatings on their leaves that allows moisture to drip off them. their roots are shallow to help them gather nutrients from the surface of the ground or directly from other plants.
